Step-by-Step Procedure of 68Ga-DOTA Triple Phase PET-CT

The 68Ga-DOTA Triple Phase PET-CT with Whole Abdomen CT is an advanced imaging procedure used to detect and evaluate tumors—especially neuroendocrine tumors—with high accuracy. Understanding the step-by-step process can help patients feel more prepared and confident before undergoing the scan.

At Molecular Diagnostics and Therapy, the entire procedure is performed with precision, safety, and patient comfort in mind.

What is This Scan?

This scan combines:

PET (Positron Emission Tomography) – detects metabolic activity

Triple Phase CT – captures detailed images in arterial, portal venous, and delayed phases

Together, they provide a comprehensive view of both the function and structure of tissues.

At Molecular Diagnostics and Therapy, this integrated approach ensures accurate diagnosis and better treatment planning.

Step-by-Step Procedure

???? Step 1: Patient Preparation

Before the scan:

You may be asked to fast for 4–6 hours

Stay well hydrated unless instructed otherwise

Inform your doctor about medications or allergies

At Molecular Diagnostics and Therapy, patients receive clear instructions to ensure optimal scan results.

???? Step 2: Radiotracer Injection

A small amount of 68Ga-DOTA radiotracer is injected into a vein

This tracer targets somatostatin receptors on tumor cells

???? The injection is generally painless and safe.

⏳ Step 3: Uptake Period

You will wait for about 45–60 minutes

During this time, the tracer circulates and binds to target cells

???? Patients are usually advised to rest and avoid movement.

At Molecular Diagnostics and Therapy, a comfortable waiting area is provided for this phase.

????️ Step 4: Positioning for the Scan

You will lie down on the PET-CT scanner table

The technologist ensures proper positioning for accurate imaging

???? Step 5: PET Imaging

The PET scanner detects radiation emitted by the tracer

Areas with high metabolic activity appear as bright spots

???? This step helps identify abnormal or cancerous cells.

???? Step 6: Contrast Injection for CT

A contrast agent is injected intravenously

This helps enhance visibility of blood vessels and organs

At Molecular Diagnostics and Therapy, contrast use is carefully monitored for safety.

???? Step 7: Triple Phase CT Imaging

CT images are captured in three phases:

Arterial Phase – early blood flow imaging

Portal Venous Phase – detailed view of abdominal organs

Delayed Phase – identifies lesions that retain contrast

???? This step is crucial for detecting liver lesions and abdominal tumors.

???? Step 8: Image Fusion and Analysis

PET and CT images are combined

Doctors analyze both metabolic and structural data

At Molecular Diagnostics and Therapy, expert radiologists interpret the results for accurate diagnosis.

⏱️ Step 9: Completion of the Scan

The entire procedure takes approximately 60–90 minutes

Patients can usually return to normal activities shortly after

What Happens After the Scan?

You may be advised to drink plenty of fluids to flush out the tracer

Results are typically available within a short time

Your doctor will discuss findings and next steps

At Molecular Diagnostics and Therapy, timely reporting ensures faster decision-making for treatment.

Is the Procedure Safe?

Yes, the scan is generally safe:

Radiation exposure is controlled

Side effects are rare

The radiotracer is quickly eliminated from the body

At Molecular Diagnostics and Therapy, strict safety protocols are followed at every step.

Benefits of This Step-by-Step Approach

Accurate and early tumor detection

Detailed evaluation of abdominal organs

Better staging and treatment planning

Reduced need for multiple tests

Patients at Molecular Diagnostics and Therapy benefit from a seamless and reliable diagnostic experience.
